roller, causing rotation of the respective cross shaft 21 and through the driven shaft 25 and its pinion engagement with the ring gear 8 to the turn-table 10.

Thus, when it is desired to utilize my improved turn-table for permitting the turning of an automobile in a relatively short space the automobile is driven upon the turn-table and its driving wheels (rear wheels) brought into engagement with two adjacent pairs of rollers 1G. It should be here explained that each pair of rollers is so spaced as to formv a shallow depression therebetween into which the wheels will drop and act as a sort ot chock to prevent movement of the vehicle while permitting thewheels thereof to rotate. It is also preferred that the'd'epressions be s o positioned that both fore and rear wheels will rest therein to thus hold the car against undesired movement.

For effecting an automatic stop of the turn-table at predetermined points I provide the table 10 with a plurality of brackets 28, each having pivoted thereto, as at 29, a lock pin 30, and being equipped with upper and lower limiting lugs 31 -lor limiting vertical movement of the said lock pins. While I have disclosed but two of the lock pin-devices and positioned them at diametrieally opposite points on the saidtable, it should be understood that these devices may be positioned atmore frequent intervals around the table if desired. vIt will be observed that the lock pins are so arranged that they project beyond the periphery of the-said turntable.

At a singlepoint on the door 1,-I secure a bracket 32 havinga lock arm 33 -pivoted thereto as at 34 anda'releasing lever 35 pivoted thereto as at 36.

The lock arm33 has-an' upwardly inclined advance cam face 3 7 leading to a lock pin receiving groove 38. The lock groove 38 t'erminates in an uprfitanding abutment or stop lug" 39 v against which the lock piu 30A movedas the turn-table reaches the position of the said lock arm and which serves to 'stop the turn-table against further movement.

To absorb the shock of this stopping olf the turn-table I provide means for permitting a yielding of the said lock arm abutmentlug. For this purpose, the bracket 32 is provided with an upstanding lug 40 and a spring 41 is interposed between the said lug' and the step lug 39. v

The lever 35 is provided with a releasing foot 42 which extends to a position beneath the lock pin 30 when in the groove 38`so that upon manipulation of the lever the said pin can be lifted `out 'of the groove 381and over thestop lug 39'to permit further rotation of In the foregoing description I have disclosed a simple andefiicient turn-table structure which vmay be rotated by power impart-V ed from the power wheels et a vehicle mounted upon the said turn-table, means being provided for safely holding the vehicle against undesired movement while the turntable is being utilized and means ali'o being provided for stopping the turn-table :it a predetermined point without undue shock or strain on the operative parts of the mechanism.

In this disclosure I have described .and illustrated one detailed embodiment of the principles of the invention but it Should be understood that other embodiments of the structure may be made such as come within the scope of the appended claims without departing from the spirit of the invention.

From the foregoing description, itv is thought the novel details 'of construction, manner ofvuse and advantages of my invention will be readily apparent to those skilled in the art to which it relates. i
